Description

Dispose the unit of air by means of controlled flow

Technical field

The present invention relates to a kind of unit of disposing air by means of controlled flow.

In more detail, the present invention relates to the application in being used for comprising the general cell of fan, perhaps more properly relate to the use of any free rotor, in the conveyor of respective direction, have single or double feed inlet, be suitable for carrying effectively and the directed air-flow that produces by free rotor.

Background technique

In the ventilation field and particularly in air disposal unit UT, the use of known free rotor, in other words do not have housing (Archimedian screw) CL, wherein application requirements it or allow its relevant with their ventilation (example that the free rotor GL of front discs DAN and rear disc DPO is housed is illustrated among accompanying drawing 1A and the 1B) with designation.

Because being extensive use of of theirs researched and developed by each MANUFACTURER in the past few years, so that be suitable for providing bigger performance of ventilating, the product of high efficiency and the output of littler noise more to market supply.

In order to obtain these results, the form of blade and inclination are shelved on (the technical know-how part of each MANUFACTURER) on one side, quite widely used technology is to use the rotation diffuser, and this rotation diffuser obtains (referring to for example GB 207741) by front discs and the rear disc that use has the rotor of the diameter bigger than blade diameter.

Diffuser and particularly rotate the research of diffuser and use and also be illustrated in B.Eck, in some communique of G.Klingenberg and F.Schlender, wherein it is generally acknowledged, slowing down in the spiral of Archimedian screw or other type or directional steering device (irrelevant with type or shape), to flow so that the part of dynamic pressure is converted to static pressure be prior art, and by obtaining similar benefit on the rotor that acts directly on use rotation diffuser.

Simultaneously, B.Eck also proposes following idea: have the diffuser of rotation DF and the free rotor GL with relative necessary commutator DL (as showing among accompanying drawing 2A and the 2B) by using in feature in the traditional Archimedian screw CL as helical geometry, can obtain the fan that combines with advantage conventional fan free rotor in theory, therefore this idea still keeps like this because do not confirmed by test.

And free rotor as known, is not have Archimedian screw and the simple rotor of tradition that uses; This is because as its basis of developing fully, and the design standard very different with the rotor that must work in housing arranged.

Spiral-shaped so really of characteristic of tradition Archimedian screw is so that the effect that increases gradually by the cross section allows the dynamic pressure component of fluid to convert static pressure as far as possible to, using it effectively in the outlet port.

Therefore, must develop relative rotor, the geometrical shape of Archimedian screw is accurately utilized and strengthened to its geometrical shape, realize the balance between scroll, entry nozzle and the commutator, this is equilibrated in this specified structure is delicate, but simultaneously, be unique in distinctive, it is the final result with directional flow of remarkable dynamic pressure component.

Therefore, infer thus, if a kind of like this conventional rotors is as free rotor, then because the interaction of shortage and Archimedian screw, and,, and obtain bad performance owing to inevitable ventilation (AERAULIC) takes place in commutator and acoustics postpones by lacking.

Free rotor designs on the one hand and is developed to, just their geometrical shape, promptly lack traditional Archimedian screw, guaranteed the highest possible static properties and efficient (being actually the characteristic of free rotor), and same geometrical shape allows also to avoid to ventilate and acoustics postpones or it decays to minimum value (lacking existing commutator) to the major general; Yet, on the other hand, there is not directional flow, but Radial Flow.

Because such difference and opposite characteristic, can understand conventional rotors easily how free rotor (because the bad performance that provides and generation of delay) can not be provided, and vice-versa, how free rotor can not be used in traditional Archimedian screw, it can constitute obstacle in the operation period of device in this case, brings non-best final properties thereupon.

Summary of the invention

In above-mentioned requirements, the objective of the invention is to avoid above-mentioned defective, and specifically, be a kind of unit, this unit permission the best and conveying and orientation flowing effectively of disposing air by means of controlled flow of manufacturing by the free rotor generation.

Another object of the present invention is, make a kind of conveyor of suitable direction, this conveyor is used to have or does not rotate diffuser and have the free rotor of single or double feed inlet, this conveyor is characterised in that, not narration more already, use the shortcoming that is arranged in the free rotor in traditional Archimedian screw and runs into.

These and other objects are realized according to unit appended technological scheme 1, that be used for disposing by means of controlled flow air by a kind of.

Preferably, by analyze by B.Eck propose about using the theory of the free rotor in traditional Archimedian screw, distinguishable its ventilates and industrial restriction, its major limitation is as follows.

At first, the rotation of diffuser means that the reservation of rotor (encumbrance) diameter is at least one size greater than blade diameter; This specific character is with the fact that needs suitable minimum range for the operational condition that guarantees free rotor in rotor and interior scroll side, promote the use of cardinal principle than the great tradition Archimedian screw, it is used in the unit uses more difficultly, yes is tending towards keeping reducing of size and reducing of thing followed manufacture cost to this current trend.

Moreover, as also indicating by B.Eck, traditional Archimedian screw, because its operation promotes the use of commutator, thereby:

-turn back in the Archimedian screw of fan in order to prevent part from flowing through the effect of rotor, pass the outlet at discharging area A place, produce the recirculation (accompanying drawing 3A has represented to be used for regional A and the regional A ' that air passes through at the place that attenuates of commutator DL) that reduces efficient;

In order to utilize distance and the relative height of Archimedian screw from rotor, obtain the optimum position that is used for the stable operation fan and limit minimum range simultaneously from rotor, in addition (move more closely), strengthen known " steam whistle effect ".

Yet, if commutator on the one hand in traditional Archimedian screw be necessary and basis (for example, as as shown in the accompanying drawing 3B, known application) with commutator DL, diffuser DF and flowing positioning device IF, made the remarkable defective of amplifying the blade tone on the other hand, then except the above-mentioned defective of size, make and using free rotor more difficult (also with regard to its voice output) in traditional Archimedian screw in the installation.

From the current known and solution that adopts, for in air disposal unit UT, using free rotor also to carry out further research and analysis, as to the edge rounding of unit UT to reduce the loss (example of the free rotor GL that in air disposal unit UT, installs that produces by their, schematically illustrate A at Fig. 4,4B, among 4C and the 4D, this air disposal unit UT has rounding and the filter F T of edge ASP), or the use of tangential fan VT (as in the example of Fig. 5), in other words, mainly be used in the fan in the civil area that is used for low/air mass flow, has low-pressure (civilian air-adjusting, family expenses ventilate, or the like), and comprise wheel and shell, the wherein aesthstic rotor that is similar to centrifugal cutter is different aspect the length of blade and structure, and wherein air flows is oriented with wheel tangent, discharge perpendicular to the rotation axis suction and with the variable-angle between 90 ° and 180 °.Yet, tangential fan VT is the product of another kind of type, have known operation and geometrical shape, also by with the tangent direction of rotor G on energy is added on the fluid (and, be unlike among the centrifugal free rotor GL that represents among Fig. 6 A and the 6B such, by rotor GL itself, make import be parallel to the axis of rotor G) and along with the direction in rotor G changes and radial discharge (as representing among the embodiment of accompanying drawing 5 and 7) is distinguished.

Embodiment

Before the characteristic of explaining in detail the unit of disposing air by means of controlled flow of the present invention, should be appreciated that, a kind of like this application of invention is not limited to the represented in the accompanying drawings CONSTRUCTED SPECIFICATION and the layout of element, because feature geometry and correct qualification size relationship allow to be used for the design and the manufacturing of the direction conveyor of free rotor, to be installed in disposing in the unit of air as target of the present invention by means of controlled flow, this conveyor has Any shape, it can be spiral, circular, oval, oblate, square with smooth bight, and can be simultaneously symmetry or asymmetrical (different shape of conveyor is illustrated among Fig. 8 A-8I and Fig. 9 A-9G, Fig. 8 A-8I represents different side profiles, and Fig. 9 A-9G represents the various views seen from the top).

Figure 10 characterization geometrical shape, and have and be suitable for being used for making the size relationship of disposing the unit of air by means of controlled flow of the present invention, this unit is called HFW-CFW, promptly be respectively the freewheel of accommodating or be contained in the interior freewheel of housing, and comprise direction conveyor CD, in this direction conveyor CD, be inserted with free rotor GL.

Specifically, also can be with reference to accompanying drawing 12 and 12A, direction conveyor CD has external casing CDA, is inserted with free rotor GL on the sidepiece F of this external casing CDA, this external casing CDA have suction nozzle with battery unit BA and with the corresponding ejection nozzle BU of the air outlet slit opening of direction conveyor CD.

Free rotor GL has central body CR, and one or two serial curved vane PL (single import or double feed inlet) is installed on this central body CR, and it may be equipped with rotation diffuser DFR; In Figure 10 and 12, also show the diameter D of free rotor GL.

According to the present invention, at first, housing CDA can have symmetric construction about the horizontal plane ∏ of the intermediate point that passes free rotor GL, perhaps it also can have non-symmetrical configuration about plane ∏, with respect between plane ∏ and plane Ω, comprise, with the appropriate section of the circumference of the perpendicular housing CDA of ∏, have radius of curvature R 1 and R2, this radius of curvature R 1 and R2 have different size, and near ejection nozzle BU with surmount plane Ω, housing CDA can have profile PP, this profile PP about and the perpendicular horizontal trajectory of plane Ω form-45 ° and+angle between 45 °.

And, the height A of the ejection nozzle BU of conveyor CD and width B have between 0.5D and the 3.5D and the corresponding size between 0.4D and 2D, and the edge BB of ejection nozzle BU is apart from the distance (the wherein diameter of D=free rotor GL) of plane Ω between 0.7D and 1.6D.

And, free rotor GL (is meant the most salient point of leaving free rotor GL in the distance D 1 of inwall between 0.15D and D from the housing CDA of conveyor CD, usually and the outward edge of the wall of blade PL coincide) locate to be inserted in the conveyor CD, and it is from the same distance D 1 of the edge of ejection nozzle BU BB (be meant the most salient point of leaving free rotor GL equally, and equally between 0.15D and D).At last, equally according to the present invention, the distance D 2 between the inwall of the housing CDA of conveyor CD and the end of each blade PL is between 0.17D and 1.12D (the wherein diameter of D=free rotor GL).

The correct application of above-mentioned geometrical relationship allows design and makes utmost point direction conveyor CD efficiently.

From text and accompanying drawing as can be known, and according to the present invention, just in the application that requires conventional steering device DL, by the profile according to conveyor CD be arranged in the housing CL and outer and be arranged on the nozzle, have multiple shape and position and the suitable direction device DA that can make up with differing from one another and resist again flow device DAR, the conveyor of fin is housed, eliminated and replaced the conventional steering device DL of known centrifugal cutter VC.

About this point, different preferred of two of direction conveyor CD but non-limiting contour representation for example are in accompanying drawing 11A and 11B, and as direction device DA's with anti-flow device DAR's again a plurality of unrestricted embodiment for example, be presented in the profile of Figure 12 B-12J and 12L-12P, the view of above Figure 12 R-12Z, seeing, in the stereogram of Figure 13 A-13D, and in the front elevation of Figure 14 A-14F.

Figure 12 and 12A partly represent as two other stereograms according to a plurality of variant embodiment of the unit of disposing air by means of controlled flow of the present invention with cross section, this unit comprises direction conveyor CD, in this direction conveyor CD, at sidepiece F place, free rotor GL is installed, be suitable for rotating on axle AG, this AG is equipped with at the suction nozzle with battery unit BA place of free rotor GL and supports S.

Specifically, Figure 12 represents not have direction and/or the anti-air disposal unit of flow device again, and Figure 12 A is illustrated in ejection nozzle BU place and is equipped with and is arranged in the possible direction device DAR that place, top and bottom locates and the possible identical air disposal unit of flow device DA again that resists.

And under proper condition, direction conveyor CD promptly has single or bivalve body CL with respect to requiring can be made into single import or double feed inlet.

The application of the invention dispose the unit of air and one of major advantage of obtaining is by means of controlled flow, and obtain the largest optimization advantages associated supplying with between power and the resulting static pressure.

Really, being known that the total pressure that is produced by the air disposal unit as fan and so on is static pressure and the dynamic pressure component sum that produces by definition, should and be the function of liquid speed, is destined to loss.

As an example, traditional in the front curve fan, in its operating point under peak efficiency (therefore, minimal noise with generation), one-component can be quantified as the 15-20% of total pressure like this, and in disposal unit of the present invention, on same operation point (by identical flow and identical static pressure identification), the dynamic pressure component has the magnitude of the 3-5% of total pressure.

And the energy (equaling energy consumption) of under any circumstance waiting to supply to the unit is the energy that must produce total pressure, perhaps more precisely also produces its dynamic component, and this dynamic component will lose inevitably.

Therefore, intuition concludes that the dynamic component of the total pressure of generation is more little, and the energy component (therefore, running cost) of the supply that loses is more little.

Also be known that, when the traditional facility of design, discharge place at centrifugal cutter VC, at least 5 times length L first delivery channel part for the diameter D that equals rotor G must keep straight line (seeing accompanying drawing 15C), because in this distance, under the situation of regular velocity distribution, a kind of as what in Figure 16, represent, the performance of entail dangers to fan VC not.

Vice versa, if do not consider such distance and install for the bend pipe that directly applies to outlet, that then for example illustrates in Figure 15 A and 15B is such, relevant with the type of the fan VC that uses, obtain even the rapid performance loss of 30-40% (maximum loss that takes place for counter-rotational fan VC is as representing among Figure 15 B); And under these conditions, turbulent flow and vortex take place inevitably, and this has the final result that noise enlarges markedly with thing followed vibration.

On the other hand, by utilizing the ventilation characteristic of disposing the unit of air by means of controlled flow of the present invention, might significantly reduce the size of facility, for the sense of rotation of free rotor GL mutually independently the possible first bend pipe PC of steering handle be directly connected to (Figure 16 A) on the discharge portion; Consider this point, for the purpose of voice output, under any circumstance suitable is, keeping the first portion of delivery channel for the length L L of the magnitude of the D of diameter at least of free rotor GL is straight line (Figure 16 B).Disposal unit manufactured according to the present invention also guarantees, flow and performance is interference-free in the outlet port, the characteristic that allows to use, such as being used for regulating directly contacting of the device that flows the buffer of SR ' or analog with the flange F L of conveyor CD, may not vibrate (as shown in the accompanying drawing 17B) relatively and can not produce the unstability and/or the thing followed, be unlike in the situation (Figure 17 A) that takes place among the traditional centrifugal cutter VC that buffer SR directly is applied in discharge on the flange.

Unit of the present invention also guarantees, suction place flow and performance interference-free, thereby can take more close suction areas AS substantially to possible wall P (typically in air disposal unit UT) to, and do not cause tangible loss.Really, one of huge restriction of the known use of fan VC in air disposal unit UT is how owing to the following fact: reduce with the distance between the suction areas AS of the wall P of unit UT and centrifugal cutter VC, will produce performance loss.Really, about this point, the publication that we quote AMCA standard 201-90 as an example, in this publication, according to the wall P of unit UT distance from the suction areas AS of fan VC, promising theory of computation performance loss and datum curve to be considered.

When the current facility of design, in order to reduce their obstacle to greatest extent, make air disposal unit UT, suppose that the distance between the suction areas AS of the wall P of unit UT and fan VC generally equals 1.0xD (the wherein diameter of D=rotor), and in most of the cases, equal 0.7xD; In practice, the performance loss of estimating to have the fan of 10% magnitude can be accepted, if this allows the size of unit UT to reduce (about this point, see side view and the square from it view of seeing of the unit UT of Figure 18 A and 18B respectively, in Figure 18 A and 18B, be illustrated in the traditional centrifugal cutter VC that has typical case's installation among the unit UT).

Yet, when available space on facility does not allow wall P to be manufactured on the distance of 0.7xD, the wall of unit UT is positioned at the 0.5xD place further, and the thing followed is significant performance loss (type according to the centrifugal cutter VC that uses has the magnitude of 20-25%) and inevitably noise increase.

On the other hand, the use of air disposal unit of the present invention, make and the wall of unit UT even to be positioned at the distance that equals 0.25xD, only have 3.5% magnitude efficient performance loss and do not have detectable ventilation loss, the thing followed is sharply the reducing (about this point of size of unit UT, see side view and the square from it view of seeing of the unit UT of Figure 19 A and 19B respectively, in Figure 19 A and 19B, be illustrated in the direction conveyor CD of the present invention that has typical case's installation among the unit UT).

Under any circumstance, for the wall P of the unit UT that is positioned at the distance that equals 0.5xD, in direction conveyor CD of the present invention, detectable loss, promptly loss in efficiency is quantified as 1-2% only.

At last, for the performance that provides, disposal unit of the present invention can be used as the selection example for the common traditional centrifugal cutter VC with single or double feed inlet, the needs that meet the demands of the performance of Gong Geiing wherein, but because its characteristic for their type uniqueness, it at air disposal unit UT (as for example air-regulon, make and discharge and electric and gas exchanger, general exchanger, electric box, the direct contacted air disposal unit of fan loop or the like) has perfect use in, with respect in said units UT, using conventional fan VC, allow to reach reduced size substantially and reduce the facility cost.

Moreover because for their not constraint or restriction of size, so air disposal unit of the present invention also can design with small size, and the field neutralization that can be used on home appliances, information technology is used in all spectra that needs directed air flows.

According to the description of having carried out, dispose the characteristic of the unit of air by means of controlled flow, target of the present invention is clearly, as advantage also be clearly.

Specifically, they are by following representative:

-in the high static efficiency direction mode of typical free rotor, use;

-producing low voice output owing to eliminating traditional commutator, it is the main cause that the blade tone amplifies;

The low dynamic pressure of-discharge place increases (values) and the largest optimization between energize and the static pressure that obtains;

-in backward rotation, use and do not have a tangible performance loss;

-flow and performance noiseless in discharge place;

-flow and performance noiseless in suction place

At last, obviously under the prerequisite that does not break away from the intrinsic novel principles of invention thought, can carry out multiple other distortion for the air disposal unit of discussing, as conspicuous, put into practice among the embodiment of the present invention, the details of illustrated material, shape and size is arbitrarily as requested, and the alternate manner of their available techniques equivalences replaces.
